Do u know π male reproduction |
AnswerΒ» Wwwooooo is it i have to read really honey<br>Male reproductive system is located in the pelvis region. It Consists of β a pair of testis, glands, accessory ducts, external genitalia.Testes-Smooth organ situated outside the abdominal cavity within a pouch calledThe ******* helps in maintaining the low temperature of the testis which is 2-2.5O\xa0C which is below than the normal internal body temperature.Each testisis 4 to 5 cm in length and 2 to 3 cm in width in adults.Each testis contains about250 compartments called\xa0testicular lobules.Each testicular lobules contain one to three highly coiled\xa0seminiferous tubules, in which sperms are produced.The wall of each seminiferous tubuleis lined by two types of cells called\xa0male germ cells (spermatogonia)\xa0and\xa0Sertoli cells.The male germ cells undergo meiosis leading to sperm formation and Sertoli cells provide nutrition to the germ cells.The regions outside the seminiferous tubules called\xa0interstitial spaces\xa0contain small blood vessels and\xa0interstitial cells\xa0or\xa0Leydig cells.Leydig cells synthesize and secrete testicular hormones called\xa0androgens.Accessory ducts-The male accessory ducts include\xa0rete testis,\xa0vasa efferentia,\xa0epididymis\xa0and\xa0vas deferens.The seminiferous tubules of the testis open into the vasa efferentia through rete testis.The vasa efferentia leave the testis and open into epididymis located along the posterior surface of each testis.The epididymis leads to vas deferens that ascends to the abdomen and loops over the urinary bladder.Vas deferens receives a duct from seminal vesicle and opens into urethra as the ejaculatory duct.The urethra originates from the urinary bladder and extends through the ***** to its external opening called\xa0urethral meatus.Accessory glands-The male accessory glands include paired\xa0seminalvesicles, prostate gland and paired bulbourethral glands.Accessory glands secrete\xa0seminal plasma\xa0which is rich in fructose, calcium and some enzymesSecretion of bulbourethral gland also helps in lubricating the *****.External genitalia-The ***** is the male external genitalia.Some special tissues make up the ***** which helps in the erection of the *****.The enlarged end of ***** called the\xa0glans *****.Foreskin, a loose fold of tissue covers the glans *****. | |
